When a received call is selected, the control unit 110 detects the selection of the received call and enters received call check mode such that the user can identify received call history information. The information displayed on the second display area can be changed and corrected by the user. When the user shifts the cursor by using direction keys of the key input unit 127, the control unit 110 detects the shifted cursor in step 206 and returns back to step 205. Through steps 204 and 205, the user can easily identify information about the displayed image data.
When the user inputs the OK key to select image data indicated by the cursor while the entire or a subset of the image data are displayed, the control unit 110 detects the input OK key in step 207, and proceeds to step 208 to display stored phone book information of a person using the selected image data. The phone information comprises personal names, phone numbers for home, mobile phone and office, image data, e-mail addresses, and the like. When the user selects the correction of image data, the control unit 110 detects the selection of the image data correction in step 209, and proceeds to step 210 to change the image data. When the user selects an image search in step 210, the control unit 110 detects the selection of the image search, and can select a type of image data stored in the memory 130 and can change and register the image data. Alternatively, the control unit 110 displays types of image data stored in a folder associated with a person, and can select, change, and register image data stored in the folder. Alternatively, when the user selects an image capture function in step 210, the control unit 110 detects the selection of the image capture function, and enters into an image capture mode. The user can select, change, and register image data captured in the image capture mode.
On the other hand, when the SEND key is input while the entire or at least a subset of the image data are displayed, the control unit 110 detects the input SEND key, and judges an input time of the SEND key in step 211. When the SEND key is pressed continuously for or greater than a predetermined time, the control unit 110 detects the SEND key pressed continuously for or greater than the predetermined time in step 212, and proceeds to step 213 to place a call to a phone number stored in a corresponding phone book associated with image data, indicated by the cursor, among the image data. The phone number used to place the call may be a phone number set as a basic value, or a phone number selected by the user. The second display area displays a phone number used to place a call. However, when the SEND key is pressed for a time less than the predetermined time, the control unit 110 detects the SEND key pressed for a time less than the predetermined time in step 212, and proceeds to step 214. In step 214, the control unit 110 controls the second display area to display number information for home, mobile phone and office stored in a corresponding phone book associated with image data indicated by the cursor. Whenever the SEND key is input for a time less than the predetermined time, the phone number information is sequentially displayed on the second display area. When the SEND key is pressed continuously for or greater than the predetermined time while the number information is sequentially displayed on the second display area, the control unit 120 detects the SEND key pressed continuously for or greater than the predetermined time, and proceeds to step 213 to place a call to a phone number displayed on the second display area.
When the MENU key is input while the entire or a subset of the image data are displayed, the control unit 110 detects the input MENU key, and controls the display unit 160 to display selection types of image data in step 220. Referring to FIG. 2B, when the image rearrangement is selected from the selection types of image data, the control unit 110 detects the selection of the image rearrangement, and displays types of the image rearrangement in step 221. When moving or still image classification or rearrangement is selected from the types of the image rearrangement, the control unit 110 detects the selection of the moving or still image classification or rearrangement, and displays types of the moving or still image classification or rearrangement in step 222. When the moving image classification or rearrangement is selected, the control unit 110 detects the selection of the moving image classification or rearrangement in step 223, and controls the first display area to display only moving images of all or a selected subset of the image data in the form of thumbnail images in step 224. In this case, the second display area displays information about a moving image on which the cursor is placed. Alternatively, when the still image classification or rearrangement is selected, the control unit 110 detects the selection of the still image classification/rearrangement in step 225, and controls the first display area to display only still images of the image data in the form of thumbnail images in step 226. In this case, the second display area displays information about a still image on which the cursor is placed. When group rearrangement is selected from the types of the image rearrangement, the control unit 110 detects the selection of the group rearrangement and displays types of the group rearrangement in step 227. When rearrangement for all groups, in other words, total group rearrangement, is selected from the types of the group rearrangement, the control unit 110 detects the selection of the total group rearrangement in step 228. The control unit 110 classifies and rearranges the displayed image data on a group-by-group basis, and controls the display unit 160 to display rearranged groups in the form of thumbnail images in step 229. In step 229, names of the rearranged groups are also displayed, and an arrangement method can be selected after a group is selected. When a corresponding group is selected from the rearranged groups, the control unit 110 detects the selected group in step 230, and controls the display unit 160 to display only image data of the selected group in the form of thumbnail images in step 231. Alternatively, when individual group rearrangement is selected from the types of the group rearrangement, the control unit 110 detects the selection of the individual group rearrangement in step 230, and controls the display unit 160 to display only image data of a selected group in the form of thumbnail images in step 231.
When selected image view is selected, the control unit 110 detects the selection of the image view and controls the display unit 160 to display types of the selected image view in step 232. When enlargement view is selected from the types of the image view, the control unit 110 detects the selection of the enlargement view in step 233, and then proceeds to step 234. In step 234, the control unit 110 enlarges only image data indicated by the cursor, and redisplays all or the selected subset of the image data. The image data on which the cursor is placed are enlarged and displayed in an image size larger than that of a thumbnail image displayed in step 204. Other image data are reduced and displayed in an image size smaller than that of the thumbnail image displayed in step 204. A thumbnail enlargement size of image data on which the cursor is placed, and a thumbnail reduction size of the other image data can be selectively set. Alternatively, when folder view is selected from the types of the selected image view, the control unit 110 detects the selection of the folder view in step 235 and proceeds to step 236. In step 236, the control unit 110 controls the display unit 160 to display types of image data stored in a folder of a person associated with information about image data on which the cursor is placed. When corresponding image data are selected from the folder, the control unit 110 detects the selected image data in step 237, and controls the display unit 160 to display the selected image data in step 238.
As it is apparent from the above description, the present invention provides a method for searching for a corresponding phone number using image data stored in a phone book, such that a user of a wireless terminal can easily search for a phone number.
